Our 04 will go 10 to 13 hours on a tank. Mostly full throttle going up our hills or more or less coasting down the other side. Seldom sits and idles so it's often pulling a trailer, hauling 20 bags of feed, green wood as high as it will go, or a load of rock/dirt for fill over and over. It's for work and it does that quite well.........
I took it for a test drive and noticed my top speed was about 32 to 35kmh. Does the top speed slow down with more weight? Or was my straight away not long enough?
